    CVE-2014-5204

    Published: 18 Aug 2014Last Modified: 10 Apr 2026

    Summary:

    Details: wp-includes/pluggable.php in WordPress before 3.9.2 rejects invalid CSRF nonces with a different timing depending on which characters in the nonce are incorrect, which makes it easier for remote attackers to bypass a CSRF protection mechanism via a brute-force attack.
